Be it known that HENRY L. MnNnaL, a citizen of the United States, residing at Baltimore city, and State of Maryland, have invented a new and useful Sifter, of which the following is aspecllication.

This invention relates to-household sifters especially designed for sifting flour, meal,

salt, or other ingredients requiring sifting. The invention -has for its objectto provide a device of this character of generally improved and simplified construction embodying a rectangular sectional body, in which the siftingdevice is operably mounted and having both ends open and adapted to be closed by removable covers, andvmore especially des gned to be operated with .one hand.

'The objects of my invention are: v

l. To provide a sitter that is reversible, in order to sift the ingredients as many times as. desired, keeping the material with` iu the sifter, untilv ready to remove.

2. To providea sitter that can be operated with one hand; also, to sift flour and the like without spilling the material, when the sifter is placed-upon any object after using.

3. To provide a sifter made in sectional parts, for the convenence of cleaning same.

In the accompanying drawing F l is a perspective view of my device partly in section, with all the parts assembled for use. Fig. 2, is a vertical cross sectional view illustrating the parts in detail.

Fig. 3, illustrates one of the avitators. Fig. et, is a view of the lever-hand e. Referring to the drawing in detail, wherein similar numerals designate corresponding parts throughout the several views, the numerals l and 3 indicate the sec-tional body parts, which are preferably rectangular formation, with open ends. A screen. or apertured partition 1l is secured centrally within the body section il by means of soldering; the edges of the screen to the walls of the body section 3. ln case aluminum ware be used for making the sifter. the edges of the screen turned to av right angle to conform to the contour of the body in order to rivet the edges of screen to the walls of the body section 3.

The agitators 4, 4, or rubbers for the screen are operable against the side faces of the partit-ion l1. These agitators being cast are of one piece, and have openings only the screen ll.

the faces of the screen l1.

between the bars or rubbers, land the apertures in center and at one side of agi-tutors. The connecting rod 12 is affixed to one-.end of the lever handle 6 while the other end of rod l2 is attached to the side of .one ofthe agtators et. Said agitators. being connected by a retaining pin l0. The said retaining pin l0 extending' through the .agitators, and rlhe retaining pin bei-ng riveted to hold the agitators firmly against These agita-tors being connected, are actuated smultaneously by the lever handle 6. The stationary handle 5 is secured to thev outer surface otsection 3 either by solder or rivets. rfhe lever handle 6 is aliixed to the stationary handle 5 by the pivot 7. The spring plate 9- io. adjustable between the handlesv 5 and G. llemovablc covers 2, 2, are provided for the open ends of the body l, l. The covers having'tlanges i3 frietionally engaging theends of said body. The body sections l, l, are tted over the flange lil-of the, body section 3.

In Fig. 2 of drawings theillustratedsectional. parts of the body are shown. The body section 3 contains the screen, lor vapertured partition l1, also the agitators l, 4. Vllhe object in forming` the body in sections, is for the convenience of assembling the parts, also to utilize the small peces of material, as well for convenient cleaning purposes.

ln Fig` 2 of the drawings, it will be observed, the agitator is formed with risers ot different heights; while near the sides, the risers are nearly flat. Tirs feature is arranged to prevent the tlour packing against the walls of the body, as the agitators are moved to and fro. in Fig. 3 only one agitator is shown, as these agitators being identical in `fr u'in, it is thought one illustration would suttice.

lu reducing my invention to practice. it is intended Vto form the fflitlerent parts. either in tin or aluminum. The stationaijv handle is secured to the outer side of section lil.

rllhe pivot 7 acts as a fulcrum for the lever handle 6. The agitatois 4. et, are actuated by this lever handle, by :i connecting rod aliixed to the agitator e. and the lever handle G. ln the center of the screen l1 there is au oblong aperture. for the pivot connecting 'the agitators to guide freely when the agitators are in operation.

Having fully described my invention, the operation is as follows y Remove the cover at one end of thesitter, place flour or other material within this end, replace the cover, press the handles together, then release the grip of the handles; repeating the operation, until the material has passed to the lower end of the sitter. If desirable to sift the material several times, invert the sifter after each operationv until the ingredients are thoroughly incorporated. Vhen sifting a small quantity o'flour at a time, leave one oi the covers'oif, and after sifting the quantity needed, allow the sitter to rest upon the closed end. This will prevent any material falling through the sitter.

`While I have herein illustrated and described structural details embodying my invention, it is understood that the invention is not limited to the particular form and arrangements of the several parts, which may be modified within the scope or' the appended claims, Without departing from Vthe spirit` of my present invention.

Having thus described my invention, what I claim is l. A sitter comprising a rectangular shaped body part, openat each end; closures forsaid open ends, an apertured partition secured centrally within said body, reciprocating agitators to operate on eachy tace of said apertured partition, a stationary handle secured to outer surface of said body, a lever handle afiixed to said stationary handle by a pivot at elbow of said lever handle, an adjustable spring plate to operate be- Macnee to outer surface of said body part, a lever handle affixed to said stationary handle by a pivot at elbow of said lever handle, an ad-A justable springplate to operate between said handles, a rod connecting said lever handle with said agitators to actuate same.

3. A sitter comprising a hollow cross sectional rectangular body part, open at eachv end; removable closures for each open end,

sieve secured centrally within the middle section of said body part, reciprocating agitators operatively mounted on opposite sides of said sieve, a stationary handle'secured to Vouter surface of said body part, a lever handle aiiiXed to said stationary handle by a pivot at elbow of saidlever handle, an adjustable spring plate to operate between said handles, a rod connecting said lever handle Awith said agitators to actuate same, said agitators being provided with risers of unequal height for the purpose shown and described.
